There is great interest today in engineering materials to have desired behaviors. One approach involves stacking atomically thin layers of different materials to achieve a complex molecular interplay throughout the stack. The resulting behavior of the stack cannot be explained by traditional theories and can only be predicted by directly simulating the layers as collections of molecules interacting with each other. Massive NAQMD and RMD simulations of functional layered materials will be validated by experiments on the same materials using a free-electron X-ray laser.

Postdoctoral Appointee – Aurora ESP – Lattice QCD Calculations for Particle and Nuclear Physics
In this position, you will research and develop massively parallel lattice quantum chromodynamics codes. The focus of the project is to deliver calculations urgently needed by experimental programs of high energy and nuclear physics, based on the computational methods of lattice quantum chromodynamics (lattice QCD). QCD embodies our most fundamental understanding of the strong nuclear force and associated particles, a key component of the more general Standard Model of particle physics. In high energy physics, lattice calculations are required to extract the fundamental parameters of the standard model (such as quark masses) from experiment. Evidence for physics beyond the Standard Model can be discovered if discrepancies are found between different methods for determining these parameters.

This project aims to advance scientific understanding of variable density turbulence and mixing, including shock interactions and near-wall effects. These apply to the mixing of the fuel capsule surface with the imploding plasma in ICF, and shock interaction with fuel streams in a supersonic jet engine as a way to improve combustion.
